scope mounting

Hi all,
I'm going to be getting a used Blaser R93 luxus. It didn't come with anything mount wise. So I ordered a 0MOA Contessa picatinny rail that is made to fit a Blaser R93 action. Question is, what height rings would i need for this rail? I'm using a 30mm tube S&B Stratos 2.5-13 x 56.
Any...
